Creativity loves routine--that is, the Muse shows up when she knows where to find us. A regular writing habit often spurs productivity.
And creativity loves change, newness, variety, the things that let fresh air and new subjects and new styles into our work. Lately I've been trying some new things, not only for the sake of creativity, but to keep my life from getting stale. I've said yes to a few opportunities that edge me out of my comfort zone.
This year I've cleared some things out of my life, and now there is room. I don't know yet exactly what will fill that room. I'm just getting ready.
